IC1396 Elephant Trunk Nebula - SHO

First full narrowband attempt. Cooler could barely keep temp a few nights and the smoke was certainly around. Not sure how that affects things. Really fun to put this together!

Processing:
1. Alignment and stacking in DSS
2. Crop
3. ABE on Ha, Sii, and OiiI
4. EZDeNoise on duplicate Ha, Sii and Oiii (x3)
5. EzDeconvolution on Ha (x1)
6. EZDeNoise on Ha (x2)
7. EZSoftStretch on Ha, Ha duplicate, Sii, and Oiii
8. PixelMath color combination - ColorMap
R: (S*0.81)+(H*0.2)
G: (H*0.9)+(O*0.1)
B: (O*0.65)+(H*0.4)
9. Invert -> SCNR (green 75%) -> Invert on ColorMap to remove purple star halos
10. StarNet++ on ColorMap for star removal
11. ColorMap CurvesTransformation for contrast etc.
12. Ha (L) CurvesTransformation for contrast etc.
13. ColorMask for localized color tweaks on ColorMap
14. CurvesTransformation for saturation and chrominance adjustments on ColorMap
15. Convolution on ColorMap
16. HDRMMT on Ha (L) order of 7 or 8
17. Unsharp mask on Ha (L)
18. ACDNR on Ha (L)
19. L combination with ColorMap with Chrominance Noise Reduction and Saturation at 0.42 (x2)
20. Save and export!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
